<p>This role provides an easy way to configure the systemd-journald
logging service.</p>
<h1 id="requirements">Requirements</h1>
<p>See below</p>
<h2 id="collection-requirements">Collection requirements</h2>
<p>If you want to manage <code>rpm-ostree</code> systems with this role,
you will need to install additional collections. Please run the
following command line to install them:</p>
<div class="sourceCode" id="cb1"><pre
class="sourceCode bash"><code class="sourceCode bash"><span id="cb1-1"><a href="#cb1-1" aria-hidden="true" tabindex="-1"></a><span class="ex">ansible-galaxy</span> collection install <span class="at">-vv</span> <span class="at">-r</span> meta/collection-requirements.yml</span></code></pre></div>
<h1 id="role-variables">Role Variables</h1>
<p>The role allows system administrator to configure basic
systemd-journald settings, through the following set of variables which
form the role's public API.</p>
<ul>
<li><code>journald_persistent</code> - boolean variable which governs
where journald stores log file. When set to <code>true</code> the logs
will be stored on disk in <code>/var/log/journal/</code>. Defaults to
<code>false</code>, i.e. <code>volatile</code> journal storage.</li>
</ul>
<p><strong>NOTE</strong>: The following settings apply to both
<code>persistent</code> and <code>volatile</code> modes unless otherwise
indicated.</p>
<ul>
<li><p><code>journald_max_disk_size</code> - integer variable, in
megabytes, that governs how much disk space can journal files occupy
before some of them are deleted. No implicit value is configured by the
role, hence default sizing calculation described in
<code>man 5 journald.conf</code> applies.</p></li>
<li><p><code>journald_max_files</code> - integer variable that governs
how many journal files can be kept at maximum while respecting max disk
size settings for journal. No implicit value is configured by
default.</p></li>
<li><p><code>journald_max_file_size</code> - integer variable, in
megabytes, describes the maximum size of single journal file. No
implicit configuration is set up by the role.</p></li>
<li><p><code>journald_per_user</code> - boolean variable, allows to
configure whether journald should keep log data separate for each user,
e.g. allowing unprivileged users to read system log from their own user
services. Defaults to <code>true</code>. Note that per user journal
files are available only when
<code>journald_persistent: true</code>.</p></li>
<li><p><code>journald_compression</code> - boolean variable instructs
journald to apply compression to journald data objects that are bigger
than default 512 bytes. Defaults to <code>true</code>.</p></li>
<li><p><code>journald_sync_interval</code> - integer variable, in
minutes, configures the time span after which journald synchronizes the
currently used journal file to disk. By default role doesn't alter
currently used value. This setting is only applicable for
<code>journald_persistent: true</code>. You will get a warning if set
otherwise.</p></li>
<li><p><code>journald_forward_to_syslog</code> - boolean variable,
control whether log messages received by the journal daemon shall be
forwarded to a traditional syslog daemon. Defaults to
<code>false</code>.</p></li>
<li><p><code>journald_rate_limit_interval_sec</code> - integer variable,
in seconds, configures the time interval within which only
<code>journald_rate_limit_burst</code> messages are handled. See
<code>man 5 journald.conf</code> for more information.</p></li>
<li><p><code>journald_rate_limit_burst</code> - integer variable, sets
the upper limit of messages from a service which are handled within the
time defined by <code>journald_rate_limit_interval_sec</code>. See
<code>man 5 journald.conf</code> for more information.</p></li>
